"So, in short, Master Plan, Part Deux is:

- Create stunning solar roofs with seamlessly integrated battery storage - Expand the electric vehicle product line to address all major segments - Develop a self-driving capability that is 10X safer than manual via massive fleet learning - Enable your car to make money for you when you aren't using it"

I take this as...

Having solar powered superchargers power autonomous semitrucks transporting cargo across america.

Having solar powered superchargers power autonomous public buses transporting people around a city.

Have my car join a fleet of uber-like autonomous teslas while i'm not using it.
